摘　　要：面向电网海量业务数据的可靠传输需求,提出一种计及双网耦合特性的电力通信骨干网业务风险自适应均衡方法。首先,构建电网-电力通信骨干网双网耦合模型,对电网节点影响下的电力业务重要度进行评估;其次,从业务层、传输层、物理层分析电力业务传输面临的风险,提出基于自适应权重的业务风险均衡优化问题;最后,利用学习拍卖算法适应业务到达与网络状态的动态变化,解决频谱竞争冲突的同时实现业务风险的自适应均衡,并理论分析全局信息未知情况下的性能损失。仿真结果表明,所提方法可有效提升电力通信骨干网的可靠承载能力,相较于传统方法降低电力业务传输风险。In order to meet the reliable transmission requirement of massive service data in the power grid,this paper proposes an adaptive risk equalization method for power services considering dual-network coupling characteristics.First,a dual-network coupling model of power grid and power communication backbone network is constructed,within which the importance of power services is evaluated considering the influence of grid nodes.Furthermore,the risks faced by service transmission are analyzed from the service layer,transmission layer and physical layer,and the risk equalization optimization problem based on adaptive weight is established.Finally,a learning-based auction algorithm is used to adapt to the dynamics of service arrival and network state,solve the spectrum competition conflict,and realize the adaptive risk equalization.Also,theoretical analysis of the performance loss with unknown global information is given.The simulation results show that the proposed method can effectively improve the reliable bearing capacity of power communication backbone network,and reduce the service transmission risk compared with traditional methods.
